Wielgus began casting early elastomers in epoxy molds back in the 1960’s, long before others were attempting it. In 1970 we were the first to cast urethane into a silicone mold
Wielgus’ molding department is specially equipped to utilize the latest technologies such as combination pressure/vacuum mold filling equipment, large and small pressure tanks, and ovens for heat curing parts (both inside and outside of the molds). We’ve also developed rigid-core boxes to maintain dimensional stability of plus or minus .005/inch.

Whether you need very large or very small parts in rigid or flexible material, color in or water clear, inserts molded in or installed, Wielgus has the equipment and expertise to do the job on time and on budget.
